An expandable shoulder trial for a reverse shoulder system is described. The trial includes a rotatably adjustable insert housed within a humeral cup. The insert has a proximal end and a distal end, the proximal end having a concave recess therein adapted to receive a glenosphere prosthesis. The distal end of the insert includes a shaft, the shaft having a helical groove disposed on at least a portion thereof. A distal end of the humeral cup is inserted in a humeral stem. The humeral cup has a proximal end including a recess therein, the recess defined by a circular wall. A guide pin protrudes from the circular wall and is adapted to engage the helical groove of the shaft of the insert. The proximal end of the insert may rotate along an axis toward the proximal end of the humeral cup and along the same axis away from the proximal end of the humeral cup.

A safety injection tank, used for quickly injecting emergency core cooling water (ECCW) to a reactor vessel in the case of a cold leg large break accident (CLLBA) in a pressurized water reactor (PWR), is disclosed. The safety injection tank has a gravity-driven fluidic device configured to efficiently change the ECCW injection mode from a high flow injection mode to a low flow injection mode. The gravity-driven fluidic device includes a spring placed in the upper end of the vertical pipe, and a vertically movable water tub placed on the spring so as to be movable in a vertical direction. When ECCW contained in the pressure vessel is discharged and the water level is reduced lower than the height of the tub, the tub is moved downwards such that the lower surface thereof comes into contact with the vertical pipe and closes the high flow inlet port.

The invention, in part, relates to the use of optogenetic methods to increase dendritic spine density on DG memory engram cells in treatment methods for memory-impairment-associated diseases and conditions.

The invention discloses an explosionproof internal-combustion forklift truck. The forklift truck comprises an operation and brake system, a dynamical system, a transmission system, an electrical system, an air intake and exhaust system, a heat exchange system and a lifting system, wherein the lifting system is fixedly connected with a truck frame of the explosionproof internal-combustion forklift truck to be used for lifting heavy cargoes; the lifting system comprises forks, a bracket and a hydraulic device; the hydraulic device comprises two stages of hydraulic cylinder assemblies arranged in the front-rear direction; each stage of hydraulic cylinder assemblies comprises a left hydraulic cylinder set and a right hydraulic cylinder set, which are respectively arranged on two sides of the bracket; a flow splitting and baffling structure is arranged at the bottom of an oil cylinder of one of the two hydraulic cylinder sets, and comprises a movable part and a fixed part, which cooperate with each other; the movable part is provided with oil ports; the fixed part is provided with flow baffling walls; the movable part is positioned at the bottom of the movement stroke of a piston rod in the oil cylinder; the piston rod can push the movable part during the movement stroke, so that the flow baffling walls can shield the oil ports. The explosionproof internal-combustion forklift truck disclosed by the invention can effectively solve the technical problems that a lifting system of a conventional internal-combustion forklift truck is liable to shake during working, and the like.

The present invention relates to porphyrins of formula (I): wherein R¹ to R⁶, R^1′ to R^6′, X, X′ Y and Y′ are as described in claim 1. The invention also relates to complexes of said porphyrins with transition metals, in particular iron, preferably as Fe(III) or Fe(0) complex, and salts thereof, use thereof as catalysts for the selective electrochemical reduction of CO₂ into CO, electrochemical cells comprising said complexes, and a method for selectively reducing electrochemically CO₂ into CO using said complexes.

The present invention relates to the medical apparatus and instruments used in the department of cardiology, especially the artificial respiration mask used in the department of cardiology. The tracheal ball is composed of a middle interval in the mask. Align the oral and nasal pouches with the patient's oral and nasal cavities, respectively. Air is blown in through the exhalation mouth, and the air pressure will open the backstop elastic flap, and the air enters the patient's body through the oral cavity, and a part of the gas passes through the patient's trachea and enters the nasal cavity through the nasal cavity. The air outlet tube ball moves upwards and crosses the air outlet position under the action of air pressure, and the gas is discharged from the air outlet. The buffer air outlet is small, and during the descent of the air outlet tube, the upper negative pressure makes the descent slower. Blowing air into the patient's mouth rhythmically makes the air out of the nasal cavity rhythmic. The beneficial effect is that the simple structure enables the doctor to be isolated from the patient's trachea and prevents the overflow of infectious germs in the patient's mouth or trachea.

The invention discloses a speed bump for highways. The speed bump for the highways comprises a base, a speed reduction seat and a plurality of airbags; the plurality of airbags are in communication with each other and horizontally arranged to form an airbag layer; the airbag layer is arranged between the base and the speed reduction seat; gas guide hoses are respectively arranged on the two sidesof the airbag layer; a surface facing a vehicle and a surface facing away from the vehicle are arranged on the speed reduction seat; the surface facing the vehicle and the surface facing away from thevehicle are obliquely arranged; a plurality of oblique convex ribs are arranged on the surface facing the vehicle; placing grooves are formed in the oblique convex ribs; and reflective films are bonded in the placing grooves. According to the speed bump for the highways, by bonding the reflective films in the grooves, the reflective films are prevented from being in direct contact with wheels tobe worn so that the reflective films are uneasy to wear and consume; in addition, the peripheral edges of the reflective films are uneasy to upturn so that the service lives of the reflective films are prolonged.

The invention belongs to the technical field of molds and discloses a guide post for an EPS (Expandable Polystyrene) plastic foam mold. The guide post comprises a base, wherein a guide sleeve is in threaded connection with the base; an end cover is arranged at the top end of the guide sleeve; a guide hole is formed in the end cover; a guide post A is arranged in the guide hole; a sliding sealing washer is arranged between the guide hole and the guide post A; a guide post B is connected to the lower end of the guide post A; a fixing plate is connected to the top end of the guide post A; a rubber blanket is arranged on the lower surface of the end cover; an elastic element is arranged between the fixing plate and the end cover; a mounting groove is formed in the lower surface of the guide post B; baffle blocks are arranged at two sides of the inner wall of the mounting groove; an iron post is arranged between the baffle blocks; a circular truncated cone is fixed on the base; a groove matched with the iron post is formed in the upper surface of the circular truncated cone; a plurality of blind holes are formed in the inner wall of the guide sleeve; a first magnet block is arranged in each blind hole. The problems that the guide post is deformed due to excessively-high descending speed thereof, and a component connected with the guide post is offset in position are solved.
